All new to me

Hi from Southern Connecticut - I'm new at all of this - No chickens yet still in the planning stage. I'd like to use part of my garage as the henhouse and I'm thinking of insulating it. Is this a good idea? My thoughts are the garage is always colder and insulating that part would keep the "someday chickens" happier.

Thanks, yes the car will still be in there - do you think it will get dusty even if it has a ceiling? The plan I have in my head would be to enclose the entire henhouse with a full door for you to enter it. I'm also thinking of using the plastic milk crates but not sure if they need to be made of wood. I know they need to be off the floor by 2ft. and the house will also have a window, which is already in the garage. I'd like to paint the inside but have read that it's not a good idea since the hens pick at everything.

Yes your garage will get very dusty, chickens and dust go hand-in-hand. It you can completely wall off a section that would help keep the dust down. And insulating is OK, but make sure you have LOTS of ventilation if you do insulate. The climate here is very cold, and my coop is insulated, but I also leave a window open all winter or have too much moisure buildup - bad for chicken lungs.
